Q1) Velocity and acceleration: a ball is thrown verticality up word from the ground level with initial velocity of 2 feet per second and initial position 10 feet. Use a(t)=2cos(2x+3)
Find the equation of the velocity of the ball
After how many seconds is the velocity of the ball one
-half the initial velocity?
Find the equation of the motion of the ball
Calculate that displacement from t=1 till t=5
seconds
